Magnets and motors 6en

Did you know that we are surrounded by magnets? They are everywhere around us and make our society work! The whole earth is actually one big magnet ...

Goal

When you are done with the work area you should be able to:

 

Carry out surveys with magnets, electromagnets.

Discuss and take a stand on issues related to the use of magnetism and electromagnetism in homes, society and nature.

Tell us how items and technical solutions with magnets and electromagnets are built to work. Tell us how they changed over time.

Assessment

During the work it will be judged whether you:

 

Do investigations of magnets, electromagnets and strength. Schedule some surveys yourself and ask good questions.

Compare your own and others survey results and provide suggestions on how the survey can be improved

Document your surveys in text and image

Exemplifies and describes magnetism, electromagnetism using the terms attract, repel, permanent magnet, magnetic field, magnetic force and electromagnetic field.

Tells about the properties of magnets and electromagnets

Describes and provides examples of how some objects and technical solutions with magnets and electromagnets are built and how the different parts interact to function

Tells how items and technical solutions with magnets and electromagnets changed over time

Teaching

During the work with the theme you will be able to:

Investigate magnet properties based on the terms attract and repel

Examine how magnets can be used to determine if other objects are magnetic or not

Investigate what a magnetic field is and how magnets can be used to detect them

Measuring a magnet's strength and how it can be varied

Investigate how electrical circuits give rise to a magnetic field

Make an electromagnet and discuss how electromagnets can be used in electrical equipment

Examine how electric power can cause magnets to rotate

1. Read and discuss the use of magnets in the home, society and nature and what the discovery of magnetism and electromagnetism means for our lives.
